Referring to FIGS. 1-8, there is shown a shifter assembly 20. The embodiment depicted includes a bezel 30 that houses the shift lever 25 that is connected to the shifter 26. The bezel 30 may include various shapes and may include various illumination patterns and other aesthetically pleasing features. The shift lever 25 may include various components including a lever member 27 and a housing 29 that may include a display portion 31 and a grip portion 33. The housing 29 may be attached to the lever member 27 using fasteners 38. It should be realized that any fastener or adhesive may be utilized.

An interlock button 44 may be received in the grip portion 33 of the housing 29. The interlock button 44 may be actuated by an operator to perform various actions. For example, the interlock button 44 may be actuated to transition the shift lever 25 and transmission into or out of a park position. Additionally, the interlock button 44 may allow transition between various positions or modes such as drive, neutral or reverse. Further, the interlock button 44 may allow the transition between automatic and manual modes of the shifter. While the interlock button 44 is shown in the grip portion 33 of the housing 29 it may be positioned at various locations that allows access by an operator.

The transmission may be actuated between various modes through movement of the shift lever 25. In one aspect, a mono-stable shifter 26 may be connected to the shift lever 25 and actuated by a tilting motion back and forth with the shift lever 25 returning to a starting position. Alternatively, the transmission may be actuated using a button 40 positioned on the shift lever 25. The display 35 may show the current mode of the transmission, as well as other information of the vehicle or an accessory 55 linked with the button 40.

Various displays including LCD, LED, OLED, VFD and other types may be positioned on the shift lever 25 in various relationships and positions. In the depicted embodiment, the display 35 is coupled to a PCB 39 which is received in the lever member 27. The display housing 31 is positioned over the display 35 and retains it in position. The display housing 31 may include a window that allows the screen to show through the housing 31. Alternatively, the housing 31 may include a clear portion that allows the display 35 to be seen. In one aspect, the display 35 may include a removable device that is positioned within a recess of the shift lever 25 or within the bezel 30. In this manner, a device such as a music player or phone or other accessory 55 having a display 35 screen may display a mode of the transmission, as well as display other information.

The shift lever 25 may have buttons 40 positioned at various locations relative to the shift lever 25. In the depicted embodiment, the buttons 40 may be positioned over the PCB 39, as described above. The buttons 40 may project through openings formed in the housing 29. It should be realized that various buttons 40 may be positioned in various locations on the shift lever 25 to provide an ergonomic and aesthetically pleasing appearance. Additionally, the buttons 40 may be integrated into the display 35. For example, the display 35 may be a touch screen that projects a button image that may be actuated by an operator.

The shift lever 25 is in communication with a shifter 26, such as the mono-stable shifter, a transmission or vehicle. Data may be received or sent by the shifter 26 or shift lever 25 to various control systems or components of the vehicle. The shift lever 25 may receive information about what images to output on the display 35 and what types of information to output. Additionally, the shift lever 25 may also receive signals concerning the lighting, backlighting of the display 35 and buttons 40. The lighting parameters may include the intensity, color or blink pattern of the display 35 or buttons 40. In addition, the shift lever 25 may transmit information to the vehicle about which buttons 40 have been depressed or actuated to control the various positions of the transmission or to control any accessory 55 that is linked with the buttons 40.

Referring to FIG. 6-8 the bezel 30 may also include a docking station 50 into which an accessory device 55 may be positioned. The accessory device 55 may be controlled using the buttons 40 on the shift lever 25 with the display 35 indicating the mode of the transmission, as well as other information of an accessory device 55. The docking station 50 may provide communication between the shifter assembly 20 and the accessory device 55, as well as provide a charging station for the accessory device 55.

The embodiment depicted in FIGS. 1-8 may include a start button 45 positioned on the shift lever 25. The start button 45 may be linked with an ignition system of a vehicle to actuate the ignition between on and off selections. In this manner, an operator may depress the start button 45 on the shift lever 25 to start and stop an engine of a vehicle. The shift lever 25 may also include the interlock button 44, as described above. In one aspect the inter lock button 44 may be positioned on the shift lever 25 such that an operator may actuate the interlock button 44 with a hand positioned over a top of the shift lever 25 or around a side of the shift lever 25.

Additionally, the shift lever 25 may include additional buttons 40. In the depicted embodiment, one additional button 40 labeled with a P may actuate the parking brake between engaged and disengaged positions. Additionally, another button 40 labeled S may adjust between various modes of the transmission including a sport mode or overdrive mode. In use, the shift lever 25 may be moved back and forth to actuate between the various modes of the transmission. It should be realized that additional buttons 40 may be included or the buttons 40 described above may be linked to other components or accessory devices.

Referring to FIGS. 7-8, there is shown a starting sequence utilizing the shifter assembly 20. As shown in FIG. 7, the start button 45 may include a background color that will pulse when the engine is in a shut down or non-operational mode. An operator may press the start button 45 thereby triggering the ignition and starting the engine of the vehicle. The display 35 may then illuminate with a start-up graphical sequence that may display various information such as the manufacturer of the shifter or vehicle or other information. The bezel 30 and housing surrounding the docking station 50 may illuminate providing an aesthetically pleasing appearance to the bezel 30 and shifter assembly 20. The information or data indicated in the display 35 may then transition to the mode of the transmission as shown in FIG. 8. An operator may then actuate the inter lock button 44 and the shift lever 25 by moving it back and forth to select various modes of the transmission.

The display 35 provided on the shift lever 25 or bezel 30 as described above may indicate various data including the mode of the transmission and menus of accessory devices linked with the shifter assembly 20 and actuated through the buttons 40. The display 35 may also provide data on actuation sequences to engage various modes of the transmission. For example, the display 35 may indicate the correct actuation sequence to shift between various modes of the transmission, such as from a park mode to a drive mode. Additionally, the display 35 may indicate the actuation sequence for shifting between other modes of the transmission such as to reverse, neutral or any of the gears associated with the transmission. In this manner, the operator of the vehicle will not be confused or need to learn various actuation sequences. The information needed to switch between the various modes of the transmission may be indicated on the display 35. In addition, the display 35 may be linked with an onboard computer to display additional information such as operating parameters of the vehicle or the status of various accessory devices 55. In one aspect, the shift lever 25 may transmit signals between the shifter, a transmission controller, an instrument cluster or other electronic control unit in the vehicle.
